SHEET-STRAIGHTENING DEVICE.

Application filed October 5,1921. Serial No. 505,660.

To all whom it may concern Be it known that l, EDWARD Born, a citizen ofthe United States, residing at Chicage, in the county of Cool: andFitate of Illinois, have invented certain new and useful Improvements inSheet-Straightening lDevices of which the following is a specification.

This invention relates to improvements in sheet straightening devices,particularly adapted though not necessarily limited in its use inconnection with automatic multigraph machines, and one of the objects ofthe invention is to provide an improved. simple, durable cheap andefficient device of this character for automatically straightening thesheets and arranging them in a straight pile as they are delivered fromthe machine.

A further object is to provide an improved machine of this characterwhich is adapted to be adjusted to compensate varying sizes of sheetsdelivered from the chine.

To the attainment of these ends and the accomplishment of other new anduseful objects as will appear. the invention con sists in the featuresof novelty in substantially the construction, combination andarrangement of the several parts, hereinafter more fully described andclaimed and shown in the accompanying drawing illustrating thisinvention and in which- Figure 1 is a top plan view of the device.

Figure 2 is a front elevation.

Figure 3 is a view taken on the left hand side of Figure 2.

Figure t is a view taken on the right hand side of Figure 2.

Figure 5 is an edge view showing a modification.

Figure 6 is a diagrammatic view of a modified form of operatingmechanism.

Throughout the specification and claims the term sheet will be employedto designate the article which is delivered from. the machine to thisstraightening device to be piled therein, but it is to be understoodthat this term is to be construed broadly so as to include not onlyasheet of paper but a card or any other article of a similar nature.

Referring more particularly to the drawing the numeral 10 designates asupporting of the support base which may be of any desired size andconfiguration and constructed of any suit able material. This basesupports the right portion of the stop 11.1, and adjacent the base ofthe upright the top is prefer ably shaped to form a handle 12 by meansof which the stop may be adjusted. To that end the stop is preferablyprovided with spaced parallel arms 13 which extend into guides orsleeves 14: formed in any suitable manner but preferably embody tubularportions secured or held in position upon the support 10 so that bygrasping the portion 12 of the stop 11 the latter may be adjusted withrespect to the guides so as to position the stop in accordance with thesize of the sheet to be delivered from the machine. If. desired anothermember 15 having spaced arms 16 may be provided at the forward end ofthe guides 1a to telescope therewith.

Later-ally disposed with respect to the stop l1 and arranged on oppositesides thereof are additional stops 17-48. The stop 17 is secured to thebase 10 for adjustment with respect thereto and in a directiontransverse to the direction of feed of the sheet in any desired orsuitable manner such by means of fastening wing nuts 19, which engagethreaded projections. 20 on the stop 17 and which projections 20 passthrough suitable slots 21 in the support 10 so that the nuts 19 will bedisposed. on the lowe= face of thesupport and by loosening these nuts'19 the stop '17 may be adjusted as desired and then secured in positionby tightening the nuts.

The stop 18 is provided with projecting portions 22 which extend throughan clon gated slot 23in the support 10 so to project therebeneath andthe slot 2 3 is of a considerable length so as to permit the stop 18 tobe reciprocated in a direction towards and away from the stop 17 andwith respect to the support 10.

Any suitable means may be provided for reciprocatingthe stop 18 but asuitable and efficient means embodies a bar or rod 2% arranged beneaththe support 10 to slide in suitable guides or bearings 25. One end ofthe element 2% is threaded as at 26 and passes through the projectingportion 12 of the stop 18. Nuts 27 engage the threaded portion of theelement 2% on opposite sides of the projection 22 so as to secure thestop 18 to the element 24 and for reciprocation therewith.

This eiement 2 1- also extends through a suitable guide or bracket 29. Alink 30 is pivotally connected by one end with the element 2st and byits other end with a rod or bar 31, which latter is aranged at a rightangle to the element 24 and passes through a suitable guide or bracket32. The free end of the element 31 is connected by means of a suitableconnecting bar or rod 33 with the operating part of the machine so thatwhen the bar 33 is moved in one of the directions indicated by the arrowin Figure 1, the bar 31 will slide through the bearing or bracket 32 andthrough the medium of the link 30 will cause the element 24; to slidethrough the brackets or bearings 2529, and cause the stop 18 to be movedtowards the stop 17. When the bar 33 is moved in the oppositedirection'the stop 18 will be correspondingly moved away from the stop17.

Another stop 3a is also provided upon the support 10 and this stop3 t isarranged opposite the stop 11 and intermediate the stops 1718. This stop'34 is adapted to be reciprocated toward and away from the stop 11 andits movement is simultaneously with the movement of the stop 18. To thatend the stop 34; is provided with a projecting portion 35 connectedtherewith and which extends through an elongated slot 36 in the support10. A bar or rod37 is arranged beneath. the support 10 which passesthrough a suitable guide 38 and also passes through the projectingportion 35 oi the element 3d. Fastening nuts 39-40 are threaded upon theelement 37 and clamp the projection 35 of the stop 34: therebetween soas to connect this stopwith the element 37. A link 11 is pivotallyconnected. by one extremity to the element 37 and by its other extremityis pivotally connected with the element 24- so that when the element Q-tis moved the stop 34- by reason of its connection therewith will. alsobe moved.

It is thought that the operation of this :device will be clearlyunderstood from the foregoing but briefly stated it is as follows. Thestraightening device with its parts shown in the position illustrated inFigure 1 is open to receive 'the sheets. As the sheets are deliveredfrom the machine they will advance in a direction toward the stop ".11and will be delivered upon the support 10 between the stops 11.'17l8-34eAfter the sheet has been thus delivered and during a further operationoi the machine the bar or rod 31 will be moved in the directionindicated by the arrow and this movement will cause the stop 18 toapproach the stop 17 and the stop 34; to approach the stop 11 so thatthese two stops 18 -34 will be given a reciprocatory movement to engagethe edges of the sheet, the stop 18 forcing the sheet towards the stop17 and the stop 34; at the same time forcing the sheet towards the stop11. As the next sheet is delivered to be superposed upon the deliveredsheets the same operation will be performed and it will thus be seenthat by continued operation or reciprocation of these stops 183t thesheets will be piled evenly upon the support 10.

By the provision of the connection as herein shown between the steps 18and 3d and their reciprocating operating elements and the adjustableconnection of the stop 17 with the support 10 as well as the adjustableconnection of the stop 11 with the support 10, it will be manifest thatthese steps may be adjusted relatively with respect to each other so asto compensate the varying sizes of sheets.

Obviously the stop 11 may be acjustably connected with the support 10 inany suitable manner such as by passing the arms 13 thereof intoapertures or openings 42 opening through the edge of the support 10.

In Figure 6 there is shown a modified form 01'? operating mechanism andin lieu of the links 30 and 11 as shown in Figure 1 bell crank levers 43and 46 are provided, the former forming a connection between the element24 and the operating rod 31 and the latter forming a connection betweenthe element 2% and the element 37.

VVhile the preferred form of the invention has been herein shown anddescribed it is to be understood that various changes may be made in thedetails of construction and in the combination and arrangement of theseveral parts, within the scope of the claims, without departing fromthe spirit of this. invention.

What is claimed as new is l. A device of the character describedembodying support, a fixed stop, a movable stop, an operating elementconnected with the movable stop, a main operating element operating atsubstantially right angles to the first recited operating element, and alink, one extremity of the link being pivotally connected with each ofthe said operating elements, the said main operating element beingmovable forwardly and backward-1y and operating to impart a positivemovement to the movable stop in both directions of its movement.

2. A device of the character described embodying sheet receivingsupport, fixed stops cooperating with the support, movable stopsco-operating with the fixed stops to engage the edges of the sheets andmove them against the fixed stops, an operating element, links detachedfrom the support and connected with the said operating element, andmeans connecting the movable stops with the respective links formovement thereby, the last recited means embodying an adjustableconnection between the links and the respective stops.

3. A device of the character described embodying a sheet receivingsupport, fixed stops co-operating with the support, movable stopsco-operating with the fixed stops to engage the edges of the sheets andmove them against the fixed stops, an operating element movableforwardly and backwardly, members connected with the said operatingelement, and means connecting the respective movable stops with the saidmembers whereby a positive movement will be imparted to the movablestops upon the movement of the operating element in each direction ofits movement, the said means embodying an adjustable connection betweenthe said members and the respective stops.

In testimony whereof I have signed my name to this specification on this1st day of October, A. D. 1921.

EDWARD BURD.
